The monitor is fine, the Atari ST however not so much (see picture below, I've asked for help in Atari-Forum.com) and no Amiga as it's not where I thought it was but is in fact in one of about 20 cardboard boxes which I don't want to rummage through.

Atari ST fixed, but cracked version of KO2 (from Automation Disk 69 part 5) does not run. Every other game/app/demo works flawlessly and I can't access my KO2 originals at the moment. I'll just bring it anyway and see if Steve's disks work.
